Vintage Question Mark Resin Shoulder Pin Brooch Signed JOY

This is a vintage pin or brooch made by @JOY. It is in the retro and whimsical shape of a question mark. It is a blue resin color with gold-tone metal edging. I think this piece would date back to the 1960 - 1970's. This piece measures about 2 1/2" in length.

This piece is in very good condition. The metal clasp pin works well. You can see the @JOY mark around the edge of the gold-tone metal.
